The limitations of photovoltaic power generation is what?

1 time cycle is limited due to the conditions of the photovoltaic power generation is out of the sun, photovoltaic power generation equipment to work normally to generate electricity. A year as a result, the day night, spring, summer, autumn and winter season has had a huge load effect on photovoltaic power generation. To cope with this situation, the electric

1 time limit due to the conditions of the photovoltaic power generation is when the sun came out, photovoltaic power generation equipment can normal work. As a result, the night of the year, spring, summer, autumn and winter load has a great influence of photovoltaic power generation. In response to this situation, the grid must be equipped with corresponding capacity under rotating standby generator. 2 location restrictions basically can only adhere to the building photovoltaic equipment for installation and construction, this is known as the local power supply of photovoltaic roof. If you leave the building to build a photovoltaic power generation, will greatly increase the cost or damage the environment and ecology. 3 meteorological conditions limit the influence of climate on photovoltaic power generation. When using photovoltaic (pv) grid power without battery, if a city's climate change is very big, power load will be volatile. Empty sky of city's air quality, such as air pollution, or deterioration of visibility, such as fog, cloudy day. , can make the photovoltaic or online real-time output decline. 4 light energy conversion efficiency is low and the traditional energy, The fossil energy, petroleum, hydropower, nuclear, etc. ) Compared to the conversion efficiency. ) Photovoltaic energy conversion efficiency is not satisfactory.
